The factory magnesium valve covers on the S65 engine are known for developing micro-porosity, corrosion, and persistent oil leaks over time. This material is highly susceptible to oxidation, leading to unsightly surface imperfections, weakened gasket channels, and sealing issues that a simple gasket replacement won't fix.

Upgrade to this high-strength aluminum valve cover set, engineered as a direct-fit replacement for your aging OEM covers. Unlike magnesium, aircraft-grade aluminum offers superior durability, enhanced heat resistance, and complete immunity to the corrosion issues that plague factory covers. Whether you're refreshing a high-mileage M3 or seeking long-term reliability, this upgrade ensures a leak-free, worry-free solution for your S65.

Features:

Eliminates the common porosity and corrosion issues found in factory magnesium covers.

Helps maintain optimal engine temperatures and enhances long-term reliability.

Designed for an OEM-like installation without modifications.

Reduces the risk of oil leaks, ensuring a proper seal.

Resistant to oxidation and chemical exposure for a long-lasting clean look.

A common cause of check engine light and limp mode after running the car hard. Restarting the car commonly clears the code and/or limp mode. Two different problem codes, 2A87 "Outlet-Vanos variable cam control test" and "2A82 Inlet-Vanos variable cam control test", are thrown indicating the possibility of various VANOS-related problems. If a solenoid valve needs to be replaced, this part is appropriate for both situations, outlet and inlet. Two required per car.

Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation

This low-pressure fuel sensor is commonly a cause of an "Increased Emissions" warning on the idrive and for check engine (SES) lights on BMW's with the N54 6 cylinder turbo engine or the S65 V8 engine in the M3. It will also fit a limited number of cars with the N55 engine. This sensor can be traced to a number of drivability issues, including cold start running problems, misfires, stumbling, hesitations, and overall rough running. You will likely have a code for the misfires, rich condition, or for the sensor itself. In some cases, the combination of codes can bring about a limp mode. Replacing this sensor is an easy and inexpensive first step if you're having any of these issues. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

Turbo Boost Leak Testers - Corporate Logo
T#:641167
Part#: BMW-N54-CAP
In Stock
$ 49.00 USD
Free Shipping on orders $49 and up
This Boost Leak Tester kit mounts inside both of the flexible intake hoses that lead to your turbo's compressor inlet flanges. You will need to remove the air box (or your aftermarket air filters) to expose the 2 intake pipes. Install the testers in each pipe and pressurize the system using the tire schrader with your tire inflation tool. The kit comes with the necessary caps to block the diverter valve return flanges on the intake pipes, also a cap to block the breather line at the bakc of the valve cover. Once the kit is installed, use compressed air to charge the system and you will see that both gauges read the compressor pressure you are filling with. You'll be able to test the turbo to the motor checking all leak points in between, including intercooler, clamped connections, intake manifold, divertor valves and the many random potential leak points. Note: Testing at the intake pipe, you may hear noise coming from the o-ring (at ~12 psi test pressure) that seals the intake pipe to the turbo inlet from debris. This is not a boost leak, these are not meant to see boost and not intended to be perfectly sealed, however hearing this hissing may be mis-diagnosed as a leak. In this case reduce the pressure. If no obvious leaks are heard in any other location, the test is complete and there are no significant leaks The gauge on the boost leak tester allows the user to: apply a safe amount of pressure to prevent injury or damage to the charge pipes or engine read how fast the system holds and bleeds air after removing the air source give a good comparison of compressor outlet air Vs. boost test air while pressurizing. The smaller the difference the lesser the air loss in the system Design Features: Plastic End Caps with 1/8" NPT threaded gauge port & fitting port Boost Gauges with 30 PSI / 1Bar Boost Gauge Universal Tire Schrader Valve (can be removed and tapped for 1/4" NPT thread fitting if desired) (2) Stainless Steel T-Bolt Clamps with Teflon lock-nut (3) Vinyl Caps for diverter valve return and valve cover breather

Free Up Real S65 Power — Engineered the Turner Way Your S65 is already making the power. This kit simply lets you keep more of it. The Active Autowerke Power Pulley Kit for the BMW E9X M3 reduces parasitic drag at the crankshaft, trimming rotational mass and freeing up horsepower that would otherwise be consumed by accessory drive load. The result is a measurable increase in rear-wheel output without sacrificing the balance, cooling capacity, or long-term durability expected from a properly engineered BMW upgrade. The crank pulley is CNC-machined from billet 6061 aluminum and finished with a hard-coat anodize for durability under sustained high-RPM operation. Unlike undersized pulleys that compromise system function, this design maintains proper operating characteristics while delivering real-world gains. Late-2007 production E9X M3 models transitioned to a double-sided (DPK) A/C belt configuration. Rather than forcing a workaround, Active Autowerke developed a proper DPK-compatible solution — including the correct matched belt. Applicable kits also include a spare DPK belt for added insurance. Dyno testing on a Mustang chassis dyno confirms gains of 10–12+ rear-wheel horsepower on an otherwise stock vehicle. Installation is fully reversible and requires no permanent modification. Product Highlights 10–12+ RWHP gain verified on stock S65 engines Complete bolt-on system CNC-machined 6061 billet aluminum crank pulley Hard-coat anodized finish for durability Includes correct replacement drive and A/C belts Spare DPK belt included where applicable Compatible with manual and DCT-equipped E9X M3 Reduces parasitic drag and rotational mass Designed to maintain proper operating temperatures Works in conjunction with Active Autowerke performance software Available for single-sided and double-sided (DPK) belt configurations Fitment Information Confirm whether your E9X M3 is equipped with a single-sided or double-sided (DPK) A/C belt prior to ordering to ensure correct application. A properly engineered solution for enthusiasts who want measurable gains while preserving OEM-level refinement and reliability.
